In the first decade of the new century, polio, a deadly and crippling infectious disease, may well be eradicated from the earth by immunization. Polio has already largely been relegated to the history books in the United States—although many people who had contracted polio in childhood suffer the muscle pain and weakness of postpolio syndrome. Consistent efforts to eradicate the disease, spearheaded by the World Health Organization and supported by the national immunization programs of most governments, are working very effectively. In the past 10 years, polio has declined by 90 percent. No antiviral therapy exists that can "cure" polio. Even if the poliovirus were eliminated in the body, damage to the nervous system is irreparable with current medical technology. Vaccines can prevent polio, but only if a person has been immunized before exposure to the virus. In 1953, Dr. Jonas Salk developed a chemically inactivated virus that immunized against the three types of poliovirus. This inert virus is given by injection and requires multiple doses. Tuberculosis (abbreviated as TB for tubercle bacillus) is a common and deadly infectious disease caused by mycobacteria, mainly Mycobacterium tuberculosis. Tuberculosis most commonly attacks the lungs (as pulmonary TB) but can also affect the central nervous system, the lymphatic system, the circulatory system, the genitourinary system, bones, joints and even the skin. Other mycobacteria such as Mycobacterium bovis, Mycobacterium africanum, Mycobacterium canetti, and Mycobacterium microti can also cause tuberculosis, but these species do not usually infect healthy adults.[1] Over one-third of the world's population now carries the TB bacterium, and new infections occur at a rate of one per second.[2] Not everyone infected develops the full-blown disease, so asymptomatic, latent TB infection is most common. However, one in ten latent infections will progress to active TB disease, which, if left untreated, kills more than half of its victims. In 2004, mortality and morbidity statistics included 14.6 million chronic active TB cases, 8.9 million new cases, and 1.6 million deaths, mostly in developing countries.[2] In addition, a rising number of people in the developed world are contracting tuberculosis because their immune systems are compromised by immunosuppressive drugs, substance abuse or HIV/AIDS. The rise in HIV infections and the neglect of TB control programs have enabled a resurgence of tuberculosis.[3] The emergence of drug-resistant strains has also contributed to this new epidemic with, from 2000 to 2004, 20% of TB cases being resistant to standard treatments and 2% resistant to second-line drugs.[4] TB incidence varies widely, even in neighboring countries, apparently because of differences in health care systems.[5] The World Health Organization declared TB a global health emergency in 1993, and the Stop TB Partnership developed a Global Plan to Stop Tuberculosis aiming to save 14 million lives between 2006 and 2015
